Also 4k average profit is very good for most people already. Not many will make such amount after taxes in normal jobs. At least not where I live. Obviously these things are relative. Avg. salary in some countries can be below 1k€ so they don't necessarily need to make even close to 4k for good living and building savings at same time.
